I didn't see you at the end...just your lady...if my memory is correct? And I invariably give a hand over including how to keep the filters clean....I'm human, so may be I err'ed. Your place is so clean...it will probably be ok ? Lift the lid on the indoor unit. It hinges at the top like a car bonnet. You system has two filters (left and right) and they are curved. Lift them up slightly and pull down to get them out. They get dirty on the outside of the curve...just wash them in warm soapy water, they can go back in wet. Reverse to refit. Don't forget the board room / office upstairs. Outside, just keep it clear of rubbish, leaves cobwebs etc, especially at the back of the unit.
It's a trap everyone. Be very careful. Not because he's looking to steal your bikes but He's wanting to see who has a damp garage so he can sell you a air con unit
A PDQ machine in your man cave...my god man...do you charge visitors for coffees or something.... They must be proud of you down at the temple.
Pulled the rear shock out the day before the TT !! In a proper Heath Robinson way my garage was full of my mate shit at the time furniture ( divorce )
